I have some of your colorful and big puzzle like Penguin on Ice, Temple Trap etc. but i didn’t expect that the smaller “IQ challenges family” can provide more fun and challenges. I just purchased this including other 7 IQ challenges in one order. And you guys make a another version of IQ Blox, IQ Steps and IQ links like making them in Pro or XXL version. And not in colorful jelly print so it will fit also to the boy/man puzzlers like me. 😊
